A classic, honey coloured, twinned calcite crystal perched on top of a dolomite matrix. This specimen comes from the "Mineralien Museum der Humboldt Universität Berlin", two old labels are coming with the piece. The matrix is in fact much larger than shown on the picture, it is easily the size of the calcite crystal, possibly even a bit larger. No damage. A classic and very aesthetic specimen! Ex Oliver Konczer collection #417.
